      drm/i915: rip out pre-production ilk cpu edp w/a · 1ce17038
      Daniel Vetter authored
      While reading docs I've noticed that this special workaround to select
      the 1.6 GHz DP clock only applies to pre-production ilk machines.
      Since the registers we're touching here are rather undocumented and
      might be harmful on later chips, rip it out.
      
      For the Bspec reference of this w/a look in "vol4g CPU Display
      Registers [DevILK]", Section 4.1.7.1 "DP_A—DisplayPort A
      Control Register", "DP_PLL_Frequency_Select".
      
      v2: Keep a debug message as a hint in case something regresses.
      Requested by Chris Wilson.

      drm/i915: move set_pll_edp to intel_dp.c · ea9b6006
      Daniel Vetter authored
      Now that we enable the cpu edp pll in intel_dp->pre_enable and no
      longer in crtc_mode_set, we can also move the modeset part to the
      intel_dp->mode_set callback. Previously this was not possible because
      the encoder ->mode_set callbacks are called after the crtc mode set
      callback.

      drm/i915: use _NOTRACE for gmbus/dp aux wait loops · ef04f00d
      Daniel Vetter authored
      Less clutter in the traces. And in both cases we yell rather loud
      into the logs if we time out. Patch suggested by Chris Wilson.
      
      v2: Annotate another I915_READ in dp_aux to be consistent - we filter
      out all register io in wait_for and similar loops. Chris also
      suggested to mark all dp_aux register access as _NOTRACE, but I think
      we should keep all functionally relevant access around, and filter
      unneeded bits in userspace after the trace is captured.

      drm/i915: irq-drive the dp aux communication · 9ee32fea
      Daniel Vetter authored
      At least on the platforms that have a dp aux irq and also have it
      enabled - vlvhsw should have one, too. But I don't have a machine to
      test this on. Judging from docs there's no dp aux interrupt for gm45.
      
      Also, I only have an ivb cpu edp machine, so the dp aux A code for
      snb/ilk is untested.
      
      For dpcd probing when nothing is connected it slashes about 5ms of cpu
      time (cpu time is now negligible), which agrees with 3 * 5 400 usec
      timeouts.
      
      A previous version of this patch increases the time required to go
      through the dp_detect cycle (which includes reading the edid) from
      around 33 ms to around 40 ms. Experiments indicated that this is
      purely due to the irq latency - the hw doesn't allow us to queue up
      dp aux transactions and hence irq latency directly affects throughput.
      gmbus is much better, there we have a 8 byte buffer, and we get the
      irq once another 4 bytes can be queued up.
      
      But by using the pm_qos interface to request the lowest possible cpu
      wake-up latency this slowdown completely disappeared.
      
      Since all our output detection logic is single-threaded with the
      mode_config mutex right now anyway, I've decide not ot play fancy and
      to just reuse the gmbus wait queue. But this would definitely prep the
      way to run dp detection on different ports in parallel
      
      v2: Add a timeout for dp aux transfers when using interrupts - the hw
      _does_  prevent this with the hw-based 400 usec timeout, but if the
      irq somehow doesn't arrive we're screwed. Lesson learned while
      developing this ;-)
      
      v3: While at it also convert the busy-loop to wait_for_atomic, so that
      we don't run the risk of an infinite loop any more.
      
      v4: Ensure we have the smallest possible irq latency by using the
      pm_qos interface.
      
      v5: Add a comment to the code to explain why we frob pm_qos. Suggested
      by Chris Wilson.
      
      v6: Disable dp irq for vlv, that's easier than trying to get at docs
      and hw.
      
      v7: Squash in a fix for Haswell that Paulo Zanoni tracked down - the
      dp aux registers aren't at a fixed offset any more, but can be on the
      PCH while the DP port is on the cpu die.

      drm/i915: use gmbus irq to wait for gmbus idle · 2c438c02
      Daniel Vetter authored
      GMBUS_ACTIVE has inverted sense and so doesn't fit into the
      wait_hw_status helper, hence create a new gmbus_wait_idle functions.
      Also, we only care about the idle irq event and nothing else, which
      allows us to use the wait_event_timeout helper directly without
      jumping through hoops to catch NAKs.
      
      Since gen2/3 don't have gmbus interrupts, handle them separately with
      the old wait_for macro.
      
      This shaves another few ms off reading EDID from a hdmi screen on my
      testbox here. EDID reading with interrupt driven gmbus is now as fast
      as with busy-looping gmbus at 28 ms here (with negligible cpu
      overhead).

      drm/i915: use the gmbus irq for waits · 28c70f16
      Daniel Vetter authored
      We need two special things to properly wire this up:
      - Add another argument to gmbus_wait_hw_status to pass in the
        correct interrupt bit in gmbus4.
      - Since we can only get an irq for one of the two events we want,
        hand-roll the wait_event_timeout code so that we wake up every
        jiffie and can check for NAKs. This way we also subsume gmbus
        support for platforms without interrupts (or where those are not
        yet enabled).
      
      The important bit really is to only enable one gmbus interrupt source
      at the same time - with that piece of lore figured out, this seems to
      work flawlessly.
      
      Ben Widawsky rightfully complained the lack of measurements for the
      claimed benefits (especially since the first version was actually
      broken and fell back to bit-banging). Previously reading the 256 byte
      hdmi EDID takes about 72 ms here. With this patch it's down to 33 ms.
      Given that transfering the 256 bytes over i2c at wire speed takes
      20.5ms alone, the reduction in additional overhead is rather nice.
      
      v2: Chris Wilson wondered whether GMBUS4 might contain some set bits
      when booting up an hence result in some spurious interrupts. Since we
      clear GMBUS4 after every wait and we do gmbus transfer really early in
      the setup sequence to detect displays the window is small, but still
      be paranoid and clear it properly.
      
      v3: Clarify the comment that gmbus irq generation can only support one
      kind of event, why it bothers us and how we work around that limit.

      Daniel Vetter authored
      Only enables the interrupt and puts a irq handler into place, doesn't
      do anything yet.
      
      Unfortunately there's no gmbus interrupt support for gen2/3 (safe for

      v3: i915_enable_pipestat expects the mask bit, not the status bits ... and
      for added hilarity those are rather inconsistently named.

      drm/i915: extract gmbus_wait_hw_status · 61168c53
      Daniel Vetter authored
      The gmbus interrupt generation is rather fiddly: We can only ever
      enable one interrupt source (but we always want to check for NAK
      in addition to the real bit). And the bits in the gmbus status
      register don't map at all to the bis in the irq register.
      
      To prepare for this mess, start by extracting the hw status wait
      loop into it's own function, consolidate the NAK error handling a
      bit. To keep things flexible, pass in the status bit we care about
      (in addition to any NAK signalling).
      
      v2: I've failed to notice that the sense of GMBUS_ACTIVE is inverted,
      Chris Wilson gladly pointed that out for me. To keep things simple,
      ignore that case for  now (we only need to idle the gmbus controller
      at the end of an entire i2c transaction, not after every message).

      drm/i915: reorder setup sequence to have irqs for output setup · 52d7eced
      Daniel Vetter authored
      Otherwise the new&shiny irq-driven gmbus and dp aux code won't work that
      well. Noticed since the dp aux code doesn't have an automatic fallback
      with a timeout (since the hw provides for that already).
      
      v2: Simple move drm_irq_install before intel_modeset_gem_init, as
      suggested by Ben Widawsky.
      
      v3: Now that interrupts are enabled before all connectors are fully
      set up, we might fall over serving a HPD interrupt while things are
      still being set up. Instead of jumping through massive hoops and
      complicating the code with a separate hpd irq enable step, simply
      block out the hotplug work item from doing anything until things are
      in place.
      
      v4: Actually, we can enable hotplug processing only after the fbdev is
      fully set up, since we call down into the fbdev from the hotplug work
      functions. So stick the hpd enabling right next to the poll helper
      initialization.
      
      v5: We need to enable irqs before intel_modeset_init, since that
      function sets up the outputs.
      
      v6: Fixup cleanup sequence, too.

      drm/i915: kill intel_dp_link_clock() · 9fa5f652
      Paulo Zanoni authored
      Use drm_dp_bw_code_to_link_rate insead. It's the same thing, but
      supports DP_LINK_BW_5_4 and is also used by the other drivers.

      drm/i915: invert the log inside intel_prepare_ddi · 0d536cb4
      Paulo Zanoni authored
      Do an early return in case we don't have DDI instead of having the
      whole function inside an "if" statement.
